Diamonds that are absolutely clear are very rare, the most sought-after and therefore the most expensive. But most diamonds have inclusions — scratches, trace minerals or other tiny characteristics that can detract from the pure beauty of the diamond. The GIA, AGS and IGI labs use a detailed system of rules and standards to summarize, note and mark the number, location, size, and type of inclusions present in a diamond.

Which Clarity Grade Is Best?
We recommend that you select an "eye-clean" diamond — one that has no inclusions visible to the unaided eye. An excellent value, diamonds of this clarity are much less expensive than IF or FL grade diamonds and typically do not contain visible inclusions that detract from the beauty of the diamond. If you're considering an SI grade diamond, call to speak to a diamond and jewelry consultant who will review the diamond to ensure the inclusions are not visible with the unaided eye. But, if you'd rather not compromise on clarity yet are budget conscious, choose a diamond with a good cut and H or lower color.

Great customer service and AMAZING product. My fiance's ring turned out PERFECT. The engravings along with the overall design of it looked amazing. These people know what they are doing. The service was great as well. I had all of my questions answered promptly and timely by the same representative all the way through. I was in a position where I had to pick my ring up in person, and the person who gave me the ring was awesome. She was a pleasure to meet, and I got the feeling they truly enjoy what they do and what they create for people.
